How do I convert J2K files?

J2K represents an upgrade of the JPEG format, including more features, such as supporting transparency and alpha channel, or lossless compression. J2K is part of a larger pack of improved JPEG extensions, known as JPEG2000, together with formats such as J2C, JPX, JPM or JP2. Most of these formats are compatible with mainstream image viewers, but do not enjoy the popularity of JPEG.

The quick and simple way to handle your files is to get a quality piece of software, such as reaConverter. This software is extremely efficient in managing a wide range of batch conversions. As you will soon realize, reaConverter will help you avoid spending countless hours trying to figure out how to convert multiple J2K files as once.
